Top commercial roofing contractors in Houston, ranked by ChatGPT answers

• Charter Roofing & Waterproofing · Roofing contractor

If you mean commercial/industrial roofing rather than residential roofers, Houston has several established options. I wouldn’t call one objectively “best,” but these are worth putting on your bid list based on commercial focus, local reputation, and the scope of work they advertise.

• Charter Roofing & Waterproofing — Long-established Houston commercial contractor; handles installation, refurbishment, repair, maintenance, and waterproofing. Its NRCA membership dates to 1981.
• Restoration Services, Inc. — Commercial roofing/building-envelope specialist with roof management, storm assessment, repair, and replacement capabilities. Its work includes flashing, drainage, expansion joints, skylights, and architectural metal.
• Brazos Commercial Roofing — Commercial/industrial specialist covering TPO, PVC, modified bitumen, BUR, standing-seam metal, waterproofing, and green roofs. It advertises emergency response and a price-match guarantee.
• Complete Commercial Roofing — Focused specifically on commercial and multi-tenant properties, including inspections, leak repair, restoration, and replacement of flat-roof systems.
• Certified Commercial Roofing — Commercial-focused contractor offering repair, leak detection, coatings/restoration, and replacement, including TPO and metal systems. It currently shows a 4.8/5 rating from 56 Google reviews on Birdeye.
• Legacy Commercial Roofing Company — Particularly focused on low-slope/flat roofs, leak repair, restoration/coatings, and maintenance programs. Angi currently shows 5.0/5 from 13 reviews.
• Chamberlin Roofing & Waterproofing — Commercial roofing plus broader building-envelope and waterproofing work, which can be useful for larger or technically complicated buildings.

How I'd narrow it down

For a large commercial building, warehouse, office building, apartment/multifamily property, or retail center, I'd get 3–4 bids and make the contractors quote the same roof system and scope. Houston's commercial-roofing market includes hundreds of contractors, so comparing apples-to-apples matters more than relying on a generic “top 10” list. The BBB directory alone currently shows 648 commercial-roofing results around Houston.

Before signing, ask each contractor for:

• Recent commercial projects similar to yours, preferably in Houston.
• Proof of general liability and workers' compensation insurance.
• Manufacturer certifications for the proposed system (TPO, PVC, EPDM, modified bitumen, metal, etc.).
• A written labor/workmanship warranty and manufacturer warranty.
• Exact tear-off, insulation, decking, flashing, drainage and curb scope.
• Who will actually perform the work—employees or subcontractors.
• References from property managers who have used them for 2+ years.
• A maintenance/inspection program after installation.

If you tell me what kind of commercial property you have (warehouse, office, retail, apartment, etc.), approximate square footage, and whether you need repair or full replacement, I can narrow this to 3–5 Houston contractors specifically suited to that project and compare their commercial specialties, reviews, warranties, and contact information.

For warehouses and industrial buildings in Houston, I’d focus less on general “commercial roofers” and more on contractors with experience in large low-slope roofs, TPO/PVC systems, metal roof retrofits, coatings, occupied facilities, and preventive maintenance programs. Houston roofs face intense UV, heavy rain, wind events, and (in some areas) industrial exposure, so industrial experience matters.

Here are several Houston-area contractors worth putting on a bid list:

Strong candidates for warehouse & industrial roofing

Other Houston contractors to consider

• Charter Roofing & Waterproofing — commercial roofing, maintenance programs, industrial coatings, metal restoration, and waterproofing services.
• Certified Commercial Roofing — focuses on commercial properties, including repairs, coatings/restoration, and replacements.
• Express Roofing & Contractor — markets commercial and industrial roofing services, including facilities such as factories and distribution centers.

What I would ask each contractor before awarding a warehouse job

For a serious industrial project, ask for:

1. Similar project references
2. Square footage of comparable warehouses
3. Roof system installed (TPO, PVC, EPDM, metal, coatings)
4. Whether the facility stayed operational during work
5. Manufacturer certifications
6. Ask whether they are certified installers for the proposed roof system manufacturer.
7. Confirm what warranty they can provide (material + workmanship).
8. Detailed scope
9. Deck repairs included or excluded
10. Insulation and cover board specifications
11. Drain and penetration detailing
12. Wind-uplift fastening design
13. Cleanup and interior protection plan
14. Maintenance capability
15. Industrial roofs benefit from inspection programs, especially after major storms.

If you tell me the warehouse size (sq ft), roof type (metal/TPO/built-up/etc.), location in Houston, and whether this is repair vs. replacement, I can narrow this to the best-fit contractors for that specific job.

• TPO Roofing In Houston · 5.0★ · Roofing contractor
• Houston Commercial Roofing and Construction · 5.0★ · Roofing contractor
• Advanced Roofing Solutions LLC · 4.8★ · Roofing contractor

If you're looking specifically for commercial TPO and flat-roof replacement in Houston, I'd build a shortlist around contractors that clearly advertise commercial low-slope/TPO work rather than general residential roofers.

Houston contractors worth getting bids from

• TPO Roofing In Houston — A particularly relevant option for a TPO-focused project. Its site says it specializes in commercial TPO systems, including installation, replacement, retrofits, inspections and maintenance, and identifies Firestone, GAF and Versico systems.
• Houston Commercial Roofing and Construction — Commercial-focused Houston contractor; worth including if you want a more traditional commercial-roofing bid.
• Advanced Roofing Solutions LLC — Established Houston-area roofing contractor with a substantial review history; I'd verify the proposed crew's specific TPO/commercial replacement experience before awarding the job.
• LOA Roofing & Construction — Their Houston commercial division explicitly handles TPO, flat roofs and replacements, as well as coatings and repairs. Their site currently reports 5.0 stars from 451 reviews.
• KBM Roofing & Restoration — Specifically advertises Houston commercial TPO installation, replacement and repair.
• Marlin Roof Systems — Offers commercial TPO, EPDM and PVC installation/repair in Houston, making them useful if you want competing membrane-system proposals rather than automatically specifying TPO.
• HHH Roofing & Construction — Advertises commercial TPO, PVC, modified-bitumen and metal systems and gives examples of completed commercial TPO replacements in Houston.
• CS Roofing Concepts — Handles commercial flat/low-slope roofs in Houston and Fort Bend, including TPO, modified bitumen, metal and fluid-applied systems.

What I'd require in the bids

For a commercial replacement, don't compare bids on price alone. Ask each contractor to specify:

1. Exact TPO manufacturer and membrane thickness — e.g. 60 mil vs. 80 mil.
2. Tear-off vs. recover — and exactly how many existing roof layers remain.
3. Deck condition and the unit price for replacing damaged decking.
4. Insulation/R-value and tapered insulation plan.
5. Drainage improvements — especially if the existing roof has ponding.
6. Fastener/adhesive and attachment method.
7. Flashing details around curbs, parapets, drains, penetrations and HVAC equipment.
8. Manufacturer warranty versus contractor workmanship warranty.
9. Whether they're a certified/authorized installer for the proposed membrane manufacturer.
10. References for comparable commercial roofs—ideally similar square footage and building use.

One particularly important issue in Houston is drainage. A good TPO membrane doesn't solve an underlying ponding-water problem; the roof design, insulation slopes, drains and penetrations need to be addressed as part of the replacement.

If you tell me the approximate roof size (sq. ft.), building type, location in Houston, and whether it's currently TPO, modified bitumen, or another system, I can narrow this to 3–5 contractors and compare their commercial/TPO credentials, reviews, warranties, and likely fit for your project.

Yes. I found several Houston-area commercial roofing contractors that explicitly advertise 24/7 or 24/7/365 emergency leak response:

• Charter Roofing & Waterproofing — Advertises 24/7 commercial leak repair, with emergency vehicles/personnel and Houston-area response “within hours” in many cases. Their commercial leak-repair page lists (713) 991-7750.
• Legacy Commercial Roofing Company — Houston-based commercial roofer advertising 24-hour emergency repair for active leaks and storm damage. (713) 347-0185.
• Marton Roofing Industries, Ltd. — Commercial-focused contractor advertising 24/7/365 emergency leak response in Houston and surrounding areas. (713) 664-7000.
• Brazos Commercial Roofing — Commercial roofing, repair, waterproofing and emergency/disaster response; the company says it is always on-call for leak impacts from severe weather and other causes.
• Delaneys Restoration Inc. — Houston contractor advertising 24/7 emergency roof repair, including active leaks, storm damage and stabilization.
• Certified Commercial Roofing — Commercial-focused Houston roofer with 24-hour listings and emergency leak/repair services.
• Partner's Commercial Roofing — Advertises 24/7/365 emergency dispatch teams and commercial leak detection/repair, including thermal imaging and drone inspection. It also lists 4-hour emergency, 24-hour priority and 72-hour standard leak-repair services.
• Sendero Commercial Roofing — Advertises 24/7/365 emergency response for critical commercial roof leaks throughout Greater Houston, with leak repair and detection. Emergency line: (713) 425-3908.

If you need someone right now

For a currently active leak, I'd call two or three simultaneously and ask specifically: “Do you have a crew available right now for a commercial roof leak, and what's your estimated arrival time?” 24/7 advertising doesn't necessarily mean a crew is immediately available.

If you tell me the Houston ZIP code and roof type (TPO, EPDM, metal, modified bitumen, etc.), I can narrow this to the contractors closest to the property and provide phone numbers, current hours, and emergency-response details.

If by “reliable” you mean established commercial capability, Houston presence, and enough public reputation to justify putting them on a bid list, I’d start with these:

• Charter Roofing & Waterproofing — 6126 Scarlet Dr. This is one of the more established Houston commercial specialists: the company says it has operated in Houston since 1968, and the NRCA directory lists it as a member since 1981. It focuses on commercial/industrial roofing, refurbishment, repair and maintenance.
• Restoration Services, Inc. — 9810 Fairbanks North Houston Rd. A commercial building-envelope contractor with capabilities across TPO, EPDM, PVC, modified bitumen, BUR, metal and coatings. Its Houston base and broad commercial-system experience make it worth getting a proposal from for substantial projects.
• Brazos Commercial Roofing — 440 Louisiana St. Downtown Houston-based, veteran-owned commercial/industrial roofing and waterproofing contractor. Particularly relevant for low-slope roofs, waterproofing and larger commercial replacements.
• Complete Commercial Roofing — 920 Memorial City Way. Commercial-focused and Houston-based, with an emphasis on inspections, repairs, restoration and replacement of flat-roof systems. Its current business listing shows 5.0/5 from 22 reviews, although that's a relatively small review sample.
• Legacy Commercial Roofing Company — Houston-based, with a 4.9/5 rating from 27 reviews in the current business data. It specializes in low-slope/flat roofs, leak response, restoration and maintenance programs.
• Samson Roofing LLC — Houston-based commercial roofer with experience in several low-slope systems; its listing also notes membership in the AGC Houston directory. Current business data shows 5.0/5 from 8 reviews, again a modest sample.

One I'd investigate carefully

Chamberlin Roofing & Waterproofing is another significant Houston commercial contractor. GAF lists its Houston operation as a GoldElite Commercial Contractor, capable of commercial roofing and liquid-applied systems. However, the current local business listing has a lower 3.4/5 rating from only five reviews, so I'd specifically ask for recent Houston commercial references before selecting them.

What I'd use to vet the finalists

For a commercial building inside Houston proper, I wouldn't choose solely from Google ratings. I'd ask each bidder for:

1. Three Houston commercial references from projects similar in size and roof system to yours.
2. The exact TPO/EPDM/PVC/modified-bitumen/metal manufacturer and system they're proposing.
3. Their manufacturer certification and the actual warranty terms—not just the headline warranty period.
4. Certificate of insurance, including general liability and workers' comp.
5. Whether the installation is performed by their own crews or subcontractors.
6. A written scope covering deck repair, insulation, drainage/ponding, flashing, penetrations and cleanup.
7. A separate price for preventive maintenance after installation.

One useful distinction: GAF certification is a meaningful credential but isn't itself proof that a particular contractor will perform well on your project. GAF explicitly says its certified contractors are independent businesses and that GAF doesn't supervise their work.

If you tell me the type of building, approximate roof square footage, and whether you need repair, coating, or full replacement, I can narrow this to 3–5 Houston contractors that are particularly suited to that specific job and compare their credentials, reviews, service area, and commercial specialties.

Yes. If by “wider Houston metro” you mean contractors willing to travel beyond central Houston into places such as Katy, Sugar Land, Pearland, The Woodlands, Cypress, Spring, Conroe, Baytown, League City, and surrounding communities, there are quite a few.

Here are some that explicitly advertise a broad commercial service area:

• Brazos Commercial Roofing — Commercial/industrial roofing and waterproofing. Houston-based, with a focus on commercial properties and broader regional work.
• Restoration Services, Inc. — Commercial roofing and building-envelope work, including re-roofing, leak diagnostics, waterproofing and restoration; serves Houston and Southeast Texas.
• Chamberlin Roofing & Waterproofing — Established commercial roofing/waterproofing contractor serving the broader Houston/Gulf Coast market, including industrial and institutional properties.
• Marton Roofing Industries, Ltd. — Commercial/industrial/institutional roofing, roof decking and architectural sheet metal; particularly relevant for larger or technically complex facilities.
• Charter Roofing & Waterproofing — Commercial/industrial roofing, refurbishment, repairs and maintenance; operating in Houston since 1968.
• CSM Industrial: A Global Company — More industrial-focused, including roofing and metal cladding for heavy industrial facilities.
• Delaneys Restoration Inc. — Commercial flat-roof repair/replacement, TPO, Duro-Last, coatings and storm restoration. Its published service area includes Katy, Sugar Land, Cypress, The Woodlands, Pasadena, Pearland, Spring, Humble, Baytown and League City.
• Complete Commercial Roofing — Sugar Land-based commercial roofer advertising service across surrounding Greater Houston communities, including Richmond, Rosenberg, Missouri City, Pearland and Katy.
• STX Roofing — Explicitly says it serves the greater Houston metro and Southeast Texas, including Beaumont, Katy, Galveston, Conroe, Cypress, The Woodlands, Pearland, League City, Sugar Land and Baytown.
• BD Roofing & Contracting — Its published commercial service area is unusually broad, listing Houston plus Pasadena, Baytown, Pearland, Sugar Land, Katy, Cypress, Spring, The Woodlands, Humble, Stafford, League City, Conroe, Missouri City, Deer Park, Manvel, Rosharon, Rosenberg, Tomball, Magnolia, Galveston, Alvin and Kemah.
• Nations Roof — A larger commercial roofing operation whose Houston team says it covers the greater Houston metro, including Sugar Land, The Woodlands, Katy, Pasadena and Pearland, with capabilities across TPO, EPDM, PVC, modified bitumen, metal and built-up roofing.
• JC&C Roofing Company — Covers both the southwest/west side and northwest/north side: Katy, Sugar Land, Missouri City, Richmond, Stafford and Pearland, plus Tomball, Klein, Spring, Cypress, Conroe and The Woodlands.

If your priority is truly commercial

I'd distinguish these from general residential roofers. For a warehouse, office building, retail center, multifamily property, industrial facility, school, medical building, or other low-slope commercial roof, the companies above that are explicitly commercial/industrial focused are the ones I'd investigate first.

If you tell me the type/size of the property and which side of Houston it's on (e.g. Katy, Sugar Land, north Houston, Baytown, etc.), I can narrow this to contractors that actually cover that area and specialize in your roof type (TPO, PVC, EPDM, modified bitumen, metal, coatings, etc.).

If by “best warranties” you mean the strongest combination of manufacturer-backed coverage + workmanship coverage + long duration, I’d focus on contractors that can issue a major manufacturer’s NDL (No Dollar Limit) system guarantee, rather than simply a contractor saying “20-year warranty.”

A few Houston-area contractors stand out from the warranty information I could verify:

The important distinction

For a commercial building, I would not choose based on “20-year warranty” alone.

For example, GAF's commercial warranty structure currently ranges from basic material warranties to much stronger guarantees. Its Diamond Pledge NDL Roof Guarantee can provide up to 35 years on qualifying systems, including workmanship coverage, labor to correct covered leaks, replacement materials, and other protections. It's available only through the highest-level GAF commercial contractors.

Similarly, Johns Manville's Peak Advantage Guarantee requires an approved Peak Advantage contractor and includes manufacturer involvement in inspection and guarantee administration.

So, for a sizable Houston commercial roof, I'd ask each bidder to put these six items in writing:

1. Manufacturer and exact roof system — TPO, PVC, EPDM, modified bitumen, coating, etc.
2. Manufacturer guarantee length — e.g. 20, 25, or 30+ years.
3. Is it NDL? A true No Dollar Limit guarantee is materially different from a prorated material warranty.
4. Workmanship coverage — how many years and who pays labor for leak repairs?
5. Maintenance requirements — annual inspections or a mandatory maintenance contract can be conditions of coverage. GAF, for example, specifically notes additional requirements for its higher-level guarantees.
6. Who actually stands behind it? Get the manufacturer's guarantee document, not just the roofer's proposal language.

My Houston shortlist for warranty-focused bidding

I'd get proposals from Houston Roofing & Construction, Restoration Services, Charter Roofing, and Priority Roofing, and ask each to quote the strongest manufacturer-backed system they can legitimately provide for your particular roof.

The key comparison isn't necessarily which contractor advertises the longest number. It's which contractor can give you the strongest manufacturer-backed guarantee for your exact roof system while also giving you meaningful workmanship coverage.

If you tell me the building type, approximate roof size, and whether it's TPO/PVC/EPDM/metal/modified bitumen (or an existing roof you want replaced), I can narrow this down to 3–5 Houston contractors and compare their actual warranty documents, exclusions, maintenance requirements, and manufacturer certifications side-by-side.

• PRC Roofing Co., Inc. · 4.2★ · Roofing contractor
• Competition Roofing Inc · 5.0★ · Roofing contractor

If by “trusted” you mean there’s public evidence that they work with property managers/building owners, have a local or family ownership structure, and have an established commercial track record, I’d put these Houston-area firms on your interview list:

• Coons Roofing — 10607 Lynbrook Dr, Houston. This is one of the clearest fits for a property-management portfolio. Coons is owner-operated, commercial-focused, and specifically structures its service around property managers: photo documentation, repair/maintenance programs, clear scopes, and direct owner involvement. Its site also shows Houston property-manager testimonials and commercial work on offices, retail, warehouses, medical buildings, multifamily and HOAs.
• Partner’s Commercial Roofing — Houston/Friendswood. Family-owned and operated since 1995, with a particularly strong property-management orientation. Partner’s explicitly lists property managers, building operators, developers and retailers as clients and offers preventive maintenance, detailed inspection reports and 24/7 emergency response. A commercial developer and other commercial customers are quoted as references on the company's site.
• PRC Roofing Co., Inc. — 3714 Osage St, Houston. A particularly interesting choice if you want a genuinely multigenerational local company: founded in 1979 by Daniel Delgado and his father, with his sons now running the commercial roofing and sheet-metal divisions. PRC says it is family-owned and self-performs 100% of its projects, rather than subcontracting the roofing labor. It handles commercial flat roofing, single-ply, modified bitumen, BUR, coatings and architectural sheet metal.
• Competition Roofing Inc — 7310 Fairview St, Houston. Family-owned commercial roofer with roots going back to 1983 and more than 40 years in the Houston market. It emphasizes in-house crews, preventive maintenance, inspections, leak repair, restoration and long-term roof-life management—services that line up well with property managers trying to avoid surprise capital expenditures.
  There is also independent reporting on the family's ownership transition, rather than the family-owned claim appearing only in the company's marketing.

How I'd narrow it down

For a property-management portfolio, I'd interview Coons, Partner’s, PRC, and Competition first. That's not a ranking of quality; they're simply the four where I found the strongest combination of local/family ownership + commercial specialization + evidence of ongoing building-owner/property-manager work.

A few things I'd ask each one before awarding work:

1. Can you provide three references from Houston property managers who currently use you for multiple properties?
2. Who actually performs the work—employees or subcontractors?
3. What's included in your preventive-maintenance program? Ask for a sample inspection report.
4. What's your emergency response SLA after a major Houston storm?
5. Which manufacturers are you certified by, and what warranty do you provide?
6. Can you give me a repair-vs.-replacement recommendation without a sales incentive tied to replacement?
7. Can you manage multiple properties under one reporting/billing system?

One distinction I'd make: “family-owned” doesn't automatically mean “good for property management.” For a PM, documentation, response time, warranty administration, after-hours service, and the ability to manage a portfolio can matter more than ownership structure.

If you tell me what kind of properties you manage (apartments, retail, industrial, office, HOA, etc.) and roughly how many roofs, I can narrow this to 3–5 Houston contractors that specifically fit that portfolio and compare their certifications, service areas, maintenance programs, emergency response, and reputation.
